基于加工特征的轴类零件三维建模方法

提出一种基于加工特征的三维建模方法,增强模型特征与加工工艺之间的关联性,以期形成轴类零部件的建模规范。通过确立特征独立性、基于加工顺序建模的两个基本建模要求,将工艺知识以建模规范的形式嵌入三维建模过程中,降低工艺人员对三维模型的辨识难度。最后,对机械轴进行三维建模,验证了该方法的可行性和有效性。

3D Modeling Method for Shaft Parts Based on Machining Features

A three-dimensional modeling method based on machining features has been proposed to enhance the correlation between model features and processing technology so as to form the modeling specification of shaft parts. By establishing two basic modeling requirements of feature independence and machining sequence modeling, process knowledge is embedded into the three-dimensional modeling process in the form of modeling specification, thus reducing the difficulty of model identification on the part of technical personnel. Finally, a three-dimensional modeling of the mechanical shafts is carried out to verify the feasibility and validity of the proposed method.
